Abstract: A bobbin unit comprising a cylindrical bobbin with reeled coil, a pole piece set in the bobbin, a magnet disposed at the edge of the poll piece, and a terminal connected to the terminal, is mounted on a stay with an engaging extrusion of the bobbin, and the bobbin unit and the stay are covered together with a body molded with resin. An "O" ring is installed between the pole piece and the bobbin.

Abstract: The present invention is directed to an electromagnetic switch that includes a casing in which are received a yoke, a bobbin, a coil, a plunger, and contacts. The plunger is formed of an electrically conductive material and the casing is formed of an insulating material. The casing comprises a square box-shaped body and a covering member fitted in an open end of the body. The yoke includes a sheet member having a generally U-shaped section and having opposite end portions between which a portion of the covering member is interposed. The opposite end portions are formed in part into at least one pair of inwardly extending lugs force-fitted in the above portion of the covering member. The covering member has a recess formed in a side surface thereof opposed to the contacts. The covering member has a partition wall formed thereon and separating the contacts from leader ends of the coil.

Abstract: An electromagnetic valve device having two electromagnetic valves comprises a solenoid unit having a unit construction in the form of a hollow cylinder and having a pair of solenoids, and a valve unit having a pair of valve mechanisms and having a unit construction in the form of a substantially solid cylinder. The solenoid unit has a pair of coil bobbins, and a pair of caps accommodating said coil bobbins. The valve unit is fitted through a central through hole of the solenoid unit and thus mounted therein. The coil bobbins are fixed to a yoke interposed therebetween and thus joined together.

Abstract: One feature of the present invention is a battery to be mounted on a vehicle, in which the battery casing is formed with a recess into which a starter magnetic switch is fitted. Another feature of the invention is a starter magnetic switch which can be fitted into the recess formed in the battery. The starter magnetic switch has a rocker means which is made of a conductive material. The rocker means has a moving electric contact which is biased normally open and which is closed when the solenoids built into the switch are energized, to close the drive circuit of a starter motor. The rocking means has one end projecting to the outside of a switch casing and is fastened to the positive terminal of the battery. In addition, a supporting means, which projects to the outside of the switch casing at the side opposed to the portion where the rocking means projects, is fastened to the negative terminal of the battery.

Abstract: A fuse circuit unit for combination with an electromagnetic switch has a first terminal having one end thereof adapted to be connected to one terminal of a main fuse of a load circuit, and another end adapted to be connected to of the input terminal of the electromagnetic switch. The fuse circuit unti also has a second terminal having one end thereof adapted to be connected to another terminal of the main fuse, and another end adapted to be connected to the load circuit, and a casing supporting the first and second terminals. The casing of the fuse circuit unit is engageable with the electromagnetic switch, and the first terminal of the fuse circuit unit is removably fastened to the input terminal of the electromagnetic switch to mechanically and electrically connect them together. The casing is molded from a resin in a one-piece body, together with the first and second terminals.
